Kernrechtsfrage
Whether the claimant's health had materially changed since the last final pension denial so as to justify a revision.
Extrahierter Entscheid
No legally relevant change in health was shown for the relevant comparison period.
Extrahierte Begründung
The prior and current records showed no objective somatic findings; the cantonal court could rely on the MEDAS psychiatric assessment and its supplement, which found dysthymia without incapacity for work and not psychosis.
